Routing Between Points with Mapbox

Routing between two points in Mapbox (Android)

You've got your lat/long order mixed up whenever you use Point.fromLngLat().

For example, dstPosition = Point.fromLngLat(dstLat, dstLng); is the wrong order.

Is there a log message in your logcat when you try the code you posted above? Search for Mbgl. Is response.body() null? Is the route size == 0? Basically, it'd be helpful if you could explain more when you say I am unable to create a route between them.

By the way, you don't have to use the Mapbox Navigation SDK for Android if you want to get a route between two points. The Mapbox Java SDK can do that.

Also, I'd move the onMapReady() stuff into the onStyleLoaded() callback.

@Override
  public void onMapReady(@NonNull MapboxMap mapboxMap) {
    mapboxMap.setStyle(Style.MAPBOX_STREETS, new Style.OnStyleLoaded() {
      @Override
      public void onStyleLoaded(@NonNull Style style) {
        map = mapboxMap;
        originPosition = Point.fromLngLat(originLng, originLat);
        dstPosition = Point.fromLngLat(dstLng, dstLat);

        MarkerOptions options = new MarkerOptions();
        options.title("Source");
        options.position(originLatLng);

        MarkerOptions options1 = new MarkerOptions();
        options1.title("Destination");
        options1.position(dstLatLng);

        mapboxMap.addMarker(options);
        mapboxMap.addMarker(options1);

        navigationMapRoute = new NavigationMapRoute(null, mapView, map, R.style.NavigationMapRoute);
        getRoute(originPosition, dstPosition);
      }
    });
  }

Routing between points with MapBox

Yes, you could use another engine for routing and just plot it as an RMAnnotation with an RMShape in the MapBox SDK.

How to plot an optimized route between multiple markers in MapBox Android Studio

You don't make a loop and call getRoute() multiple times. You should call getRoute() once and pass it all of the points. You set the origin and destination as you have done (in this case destination should be the last point in the list). All the intermediate points are set by calling addWaypoint().

If you want to return to the start point then you should set the destination = origin.

Mapbox draw direction via two markers

If I understand correctly, you wish to use Mapbox's direction and routing layer to get the walking route between the two points and display it. To do so you need to set the origin and destination points and call the query() function of direction. You also need to add a routes control to the map. The revised code is as follows.

// example origin and destination
var start = {lat: 22.3077423, lng: 114.2287582}; 
var finish = {lat: 22.3131334, lng: 114.2205973};

var map = L.mapbox.map('map', 'mapbox.streets', {
    zoomControl: false }).setView([start.lat, start.lng], 14); 

map.attributionControl.setPosition('bottomleft'); 
var directions = L.mapbox.directions({
    profile: 'mapbox.walking' 
});

// Set the origin and destination for the direction and call the routing service
directions.setOrigin(L.latLng(start.lat, start.lng)); 
directions.setDestination(L.latLng(finish.lat, finish.lng));   
directions.query(); 

var directionsLayer = L.mapbox.directions.layer(directions).addTo(map); 
var directionsRoutesControl = L.mapbox.directions.routesControl('routes', directions)
    .addTo(map);

You may not need to add the origin / destination markers yourself, as origin / destination markers would be displayed as part of the directions control.
